摘要
中亚成矿域夹持于东欧、西伯利亚、塔里木和华北克拉通之间,是全球重要成矿域之一。本文以中亚成矿域古生代时期的斑岩铜(金、钼)矿床作为研究对象,通过分析中亚成矿域南北两个斑岩铜矿成矿带内主要斑岩型矿床的空间分布规律,发现该时期主要的斑岩型矿床在空间分布上具有明显的等距性规律,相邻矿床等距分布的间距范围为385±25km。在此基础上指出新疆托克逊县以南-库米什一带、内蒙古额济纳旗以东中蒙边境附近、内蒙古二连浩特市一带是中亚成矿域古生代斑岩型铜(金、钼)矿床成矿的重要空间节点,目前尚未在斑岩铜(金、钼)矿找矿中取得突破,在今后的找矿工作应引起重视。
The Central Asian metallogenic domain,sandwiched between Eastern Europe,Siberia,Tarim and the North China Craton,is one of the important metallogenic domains in the world.Taking the porphyry copper(gold,molybdenum)deposits in the Paleozoic era of the Central Asian metallogenic domain as the research object,this paper analyzes the spatial distribution law of the main porphyry type deposits in the two porphyry copper metallogenic belts in the north and south of the Central Asian metallogenic domain,and finds that the spatial distribution of the main porphyry type deposits in this period has obvious isometric law,and the spacing range of the isometric distribution of adjacent deposits is 385±25 km.On this basis,it is pointed out that the area from the south of tuokesun County in Xinjiang to kumish,the east of Ejina Banner in Inner Mongolia near the Sino Mongolian border,and the area of Erenhot city in Inner Mongolia are important spatial nodes for the mineralization of Paleozoic porphyry copper(gold,molybdenum)deposits in the Central Asian metallogenic domain.At present,no breakthrough has been made in the prospecting of porphyry copper(gold,molybdenum)deposits,and attention should be paid to the prospecting work in the future.
